It is certain that if a Tages had cleansed our whole race of its deformities, and if an analogous morality had rendered us indifferent to the illnesses, weaknesses, and sufferings of humanity, regenerative science would not have been able to arise. It is only by recognizing the effects that we can go back to the unhealthy causes, and save humanity from danger. The _causes_ of death are as invisible and intangible as microbes; man may drink poison when he thinks he is drinking nectar. Woe to us if the diseased and degenerate did not exhibit themselves to us as an advance guard, to testify to the unconscious errors which threaten us with perdition. Science does not exactly limit itself to tending the sick, like the _personnel_ of a hospital, but it penetrated by that goodly door, and made its way in a contrary direction towards a normal humanity, unconscious of its danger. The ultimate result of science is not the care of the sick but universal health. We owe the hygienic "comfort" which ensures our health, and diminishes general mortality to so great an extent, to the fact that sick people were collected together and tended. The promise of regeneration given us by eugenics, which offers us the universal hope of a more flourishing and happier generation than that of the past has been made possible because we mercifully collect all the feeble-minded, the epileptics and the unhealthy. It was to this we had to look in order to find the roads which lead to health, and arrive at the gates of a better world. When Christ showed the way of salvation to men He pointed to those who were rejected by society, in whom the obvious effects of evil could be seen, because the causes of evil are too subtle, and are not always directly visible: "You hear with your ears and do not understand; you behold with your eyes and do not see."
